Cut the watermelon into cubes and place in a large bowl. If using cherry tomatoes, cut them in half and add to the watermelon.

Grate the halloumi using the coarse side of a grater and sprinkle evenly over the salad. Alternatively, you can cut the cheese into slices, grill on both sides until golden, and arrange on top.

Finely chop the chilli. If you prefer a milder flavour, remove the seeds first. Add to the salad along with the torn mint and coriander leaves.

Drizzle the salad with lime juice just before serving. Serve immediately, preferably well chilled.
